Command prefix is C-b. This can be changed by building with, for example: META='\001' make Key bindings: d detach c create new window n next window p previous window l last (next to last selected) window r refresh screen w list current windows i show window info 0-9 select window There is one default server process per user which puts its socket in /tmp/tmux-UID. It is created the first time tmux is run and subsequent invocations will connect to the same server. The server holds multiple sessions. Syntax is: tmux [-v] [-S path] command [flags] -v Create logfiles, verbosity increases with more -v -S Set different server socket path Commands: (Commands can be shortened, as long as they are unambiguous) new-session [-s ] [-d] Create new session. Attaches to new session unless -d is given. attach [-s ] Attach to session. list-sessions List sessions (can be shortened to ls). list-windows [-s ] List windows (can be shortened to lsw). rename-window [-s ] [-i ] name Rename window. If a session name is not given, the current session is assumed if a command is run from inside tmux and the TMUX environment variable is available, otherwise if only one exists, it is used or if multiple exist, an error is generated. Sessions are destroyed when no windows remain attached to them. You might get message "couldn't find server" after a crash, in this case you must remove the /tmp/tmux-`id -u` file manually.
